Question

закончите уравнения реакций, расставьте коэффициенты, укажите тип реакции. подчеркните формулы сложных веществ. Al+Fe2O3=; C+S=; NH3=; Mg3N2=.

Answer 1

2AL+Fe2O3=2Fe+AL2O3 замещения

C+2S=CS2 соединения

2NH3=N2+3H2 разложения

Answer 2

Reactions and equations:

The reactions and equations are as follows:

Al + Fe2O3 → Al2O3 + 2Fe This is a substitution reaction where aluminum replaces iron in iron(III) oxide. Aluminum oxide (Al2O3) and iron are the products.

C + S → CS2 This is a direct combination reaction between carbon and sulfur to form carbon disulfide (CS2).

3H2 + N2 → 2NH3 This is a synthesis reaction where nitrogen and hydrogen combine to form ammonia (NH3).

2Mg + N2 → Mg3N2 This is another synthesis reaction, where magnesium and nitrogen react to form magnesium nitride (Mg3N2).
